How do I interpret the result of the magnetic scale?

If you get a positive result from the magnetic balance, then the material at hand is diamagnetic. If the result is weakly negative, then it is paramagnetic and if it is strongly negative, then the object is probably ferromagnetic. In most cases, a negative result means that the test piece is not a pure precious metal. However, there are some exceptions to consider: e.g. older Krugerrand coins.
